In affluent societies, regular, vascular aerobic physical activity strengnthens all of the major body systems and, along with diet and stress management is the foundation of good health.
The most immediate benefit of aerobic physical activity is that you feel better. The mind is just another body system, and like all body systems works better when you're aerobically fit.
Aerobic exercise stimulates the elimination system, the lungs, respiratory system, lymphatic and blood systems, liver, digestive system and the kidneys.
We live in an age when more and more people have over-stimulated sympathetic nervous systems, particularly people cooped up in offices, trucks and cars all day. The fight response that starts with the mind and then works through the endocrine system produces muscle tension, constricts blood vessels and alters a range of body functions. Aerobic exercise acts like a metabolic defrag and calms down an over stimulated sympathetic nervous system.
It overcomes insulin resistance. The major cause of adult onset diabetes is insulin resistance in the muscles due to lack of regular, vital physical activity. Whilst physical activity may not completely fix up a dysfunctional pancreas, it will go a long way toward enabling diabetics to manage type II diabetes without medication.
Vigorous physical activity stimulates the immune system through corticosteroid production and the increase of white blood cells. When the immune system is strong, you are more resistant to colds and flu. You have an enhanced ability to deal with allergic reactions and you're less at risk of cancer.
Elevated blood pressure is directly related to motion starvation. For the greater proportion of people, training aerobically, with vigour for 40 minutes each day will restore blood pressure to normal.
It reduces the risk of heart attack. Cardiac dysfunction usually comes at the end of a long chain of dysfunctions (autonomic nervous system, elimination system, liver …). The status of all these systems is improved by regular, systematic and vital physical activity.
It clears the respiratory tract. Ever person with a regular aerobic training program knows that physical activity has a wonderful effect on clearing the respiratory tract. One wonders how it gets 'cleaned up' under normal circumstances without the stimulation of the lungs and warmth of the body.
It stimulates the bowel. Anyone who runs or exercises with vigil knows that the digestive system works better. One has to wonder at where the gas discharged during activity goes when there is no activity!
There is an epidemic of heads in Western countries. Headache is the most popular symptom of poor health that people experience (and ignore). Headaches have many causes. However, what we know is that people who are fit and healthy do not get them. If you want to have few headaches, do what fit and healthy people do. They train.
Aerobic activity burns off body fat. It is a tough assignment in an affluent society expecting to stay at your ideal weight without a regular fitness training program. Once the activity level drops you can be certain that sooner or later you'll start stacking on the weight. A reasonable body fat for men is less than 20% fat, and for women less than 30%.
Aerobic physical activity ensures that your brain gets more oxygen. That's another reason why you feel better.
It increases your energy level. There is a universal law which says that if you want more energy you need to use more up.
It stimulates the endocrine system to release of a range of 'good' chemicals. When you exercise with reasonable vigour for about 30 minutes or more, your endocrine system clicks into gear. One of the better known effects is the release of endorphins (that is, naturally occurring opiates) from the brain, bringing about a naturally occurring high: – you feel better. You have more energy and vitality.
When you are vigorously physically active you'll sleep better. That comes from Nathan Pritiken who said that if you do not have time to exercise take an hour off your sleep. Not only will you sleep better, you'll need less sleep.
Regular vital physical activity has a wonderful effect on improving libido. A reduced libido is a symptom of poor general health. It is dramatic evidence that a number of body systems are not working properly, from the head down. Increase your aerobic fitness and you'll end up lean as a greyhound and toey as a Roman sandal.
